Carrie is enjoying all the perks of living a double life, having realized that she is actually a great liar. She is pretending to go to her internship at the law firm, while actually going to her internship at Interview Magazine, where they think she is at least 19. She's also busying herself pretending not to like Sebastian anymore, who is planning to break up with Donna LeDonna.
In high school life, Walt and Donna are in charge of a lock-in. Carrie gets invited to an Interview party at a club called Limelight the same night, and chooses to avoid Sebastian and party in New York. Maggie is struggling with her secret that she cheated on Walt, and plans to tell him at the lock-in before Donna can reveal the truth.
Sebastian dumps Donna, but she requests that he not tell anyone. The only point of this is to cause more miscommunication with Carrie and all her friends, who are very intent on finding out Sebastian's true feelings. Once Mouse and Maggie discover that Sebastian has already broken up with Donna, they encourage him to go get her in a grand gesture at Limelight.
Tom, Carrie's dad, is also out in the city, on a double date with Harlan. Why anyone is friends with Harlan at all remains a mystery, but he's good for getting Tom out. Tom hits it off with Harlan's date's cousin, and the four of them decide to go to, you guessed it, Limelight.
Carrie, buzzing off her first Cosmopolitan from a long-haired city boy, dances on a pedestal at the club. She sees her dad dad-dancing up on this strange woman, and freezes on the pedestal just long enough for him to see her. He pulls her away, Larissa intervenes, and all the skeletons in Carrie's closet come tumbling out at once. Carrie is not working at the law firm, she's 16, and she's drunk at a club in New York. Larissa doesn't care that Carrie is 16, but Tom wants to pull her away from Pleasure Island as soon as possible.
Sebastian and Mouse get stuck in traffic, are too late to find Carrie in the club, and Sebastian's car gets towed. No word on how they get home.
Meanwhile, at the lock-in, Donna traps Walt in the projection room and tells him Maggie's secret. Walt dumps Maggie once and for all, and makes out with Donna because they are both broken-hearted. The day, Donna proclaims Walt her boyfriend, and Walt accepts because it's easier to pretend to be into Samantha Baker than to admit to being into Jake Ryan.
Carrie asks her dad for forgiveness, and makes a plea worthy of a few months in a law firm internship. She tells her father that she has discovered she wants to be a writer. He tells her she's 16, she doesn't know what she wants. Dorrit is nowhere to be seen in this episode, by the way. So Carrie is banned from Manhattan, which should give her a chance to start dating Sebastian again now that all that is cleared up. Just when things were starting to get interesting, we have to care about Sebastian again.
